Concept Mapping




    1. Toggle Edit Mode On

    To begin editing the visual graph, locate the "Edit mode" toggle in the top-right corner of the interface. Clicking on this toggle will switch the editor to "Edit mode on," enabling the functionality to add, edit, or map concepts within the canvas. The green indicator confirms that edit mode is active, allowing you to make changes to the graph seamlessly.

    2. Search for Concept to Map

    Once edit mode is enabled, navigate to the left-side panel and select the Search tab. In the search bar, type a keyword (e.g., "NDVI") related to the concept you want to map. The search feature will look for relevant concepts in the existing Body of Knowledge (BoK), helping you identify terms or entities available for addition to your graph.

    3. Search Concept from Existing Body of Knowledge

    After entering a keyword in the search bar, the system will display a list of search results fetched from the Body of Knowledge. Review the results carefully to locate the exact concept you want to map. For example, you might find the Normalized Difference Vegetation Index (NDVI) listed with its associated description and reference link.

    4. Add Concept from Body of Knowledge to Canvas

    When you identify the desired concept in the search results, click the green "Add" button next to the concept name. This action will place the selected concept as a node onto the visual canvas. By adding it, you begin building or expanding the knowledge graph with the chosen concept as a visual entity.

    5. New Concept from Body of Knowledge Will Appear in Canvas

    After clicking the "Add" button, the selected concept will immediately appear on the canvas as a new node. This visual representation allows you to see the concept in context with other nodes and relationships. For instance, the Normalized Difference Vegetation Index (NDVI) node will be displayed as part of your knowledge graph.

    6. Click Concept Source to Toggle Relation Node Bubble

    To explore relationships or create connections, click on the newly added node on the canvas. This action will toggle a relation node bubble, often represented with a small bubble. The bubble allows you to map relationships between nodes, such as linking concepts, or resources, enabling a more comprehensive graph structure.




    1. Double-click on a Relation to Show the Edit Modal and Update the Relation Type

    To modify an existing relationship between two nodes, double-click on the relation line within the canvas. This action will open the "Edit modal" window, where you can update the relationship properties. The modal will allow you to make changes such as the relation type, label, or comments associated with the selected edge.

    2. Select the Relation Type from the Dropdown Menu

    Within the "Edit modal" window, navigate to the Type dropdown field to choose a new relation type. Options like owl:objectProperty, owl:sameAs, rdfs:SubClassOf, or owl:equivalentClass are available. Simply click on the desired option to replace the existing relation type with the appropriate classification for your knowledge graph.

    3. Save the Edit to Update the Relation

    Once you have selected the correct relation type and made any necessary changes, click the green Save button at the bottom of the "Edit modal" window. This will confirm your changes, updating the relationship between the nodes on the canvas and reflecting the modified relation type.
